(139 words) Self-doubt is a person’s inability to value himself.
In the proposed text, the opinion of strangers turned out to be decisive in the personal file of Venka, which concerned his appearance: is he wearing a jacket or not. The boy listened to classmates, and not himself, because he was not sure of his own judgments, he thought that strangers knew more about him than he did. This is the wrong position, because it belittles a person.
The same problem was described by N.V. Gogol in the novel The Overcoat. Akaki Akakievich put all his feelings into the thing, because it exalted it, according to others. Not the person painted this overcoat, but vice versa. Therefore, he died, having lost her, as a chance for public recognition. If he had enough self-confidence, he would not have taken this loss so painfully.
Thus, self-doubt is a flaw that enslaves a person and prevents him from thinking with his own head.
Example from the movie: In Jake Kazdan’s film “Jumanji: Call of the Jungle”, the main character in real life lacked self-confidence: he was a quiet, timid and inconspicuous boy. But in the game, Spencer became a powerful and powerful character who was supposed to win. Then he had the long-awaited quality, but not because of physical strength, but because of the understanding that the fate of friends depended on his actions. Having returned, the hero realized that for success it is necessary to maintain normal self-esteem.
Personal life example: Recently I heard a story about a girl who was shy of her fullness and was unable to dance because of this, although she did it very well. She left the dance section, became isolated in herself, and all because her envious friends told her offensive words. Now she is trying to lose weight, but in vain, because she needs not to lose weight, but to restore objective self-esteem.
Media example: In one newspaper, I read an article about Mark Zuckerberg, the founder of Facebook. It said that this rich, successful and educated person was a shy and reserved student, who, in the end, was expelled from the university. However, Mark did not lose heart, doubting himself, but realized his plans and succeeded. And all because he managed to raise his self-esteem over the opinions of others.
